The Flat Display Mounting Interface (FDMI), also known as VESA Mounting Interface Standard (MIS) or colloquially as VESA mount, is a family of standards defined by the Video Electronics Standards Association for mounting flat panelmonitors, TVs, and other displays to stands or wall mounts. It is implemented on most modern flat-panel monitors and TVs.

The first standard in this family was introduced in 1997 and was originally called Flat Panel Monitor Physical Mounting Interface (FPMPMI).

The original VESA mount (MIS-D) consisted of four screws arranged in a square, with the horizontal and vertical distance between the screw centers being 100 mm. This is still the most commonly used configuration for desktop computer displays. A 75 mm × 75 mm layout was defined for smaller displays.

The MIS-D screw holes have an M4 thread and are typically 10 mm deep. Appropriate fasteners (typically ~10 mm long) are often supplied with the mount rather than the display, but they are also easily available from many hardware stores.

The FDMI was extended in 2006 with a collection of additional screw patterns that are more appropriate for larger TV screens.

VESA has developed a set of standards for the manufacturing of flat screen televisions and PC monitors. Most manufacturers comply with this standard by adhering to an industry wide “hole pattern” on the back of their displays for mounting purposes. A typical VESA hole pattern for flat panel displays can be one of the following sizes:

75 mm x 75 mm (75 mm = 2.95 inches)

100 mm x 100 mm (100mm = 3.94 inches)

200 mm x 200 mm (200 mm = 7.87 inches)

400 mm x 400 mm (400 mm = 15.7 inches)

600 mm x 400 mm (600 mm = 23.57 inches)

800 mm x 400 mm (800 mm = 31.5 inches)

For example a typical Samsung 42" and higher uses a 600x400 Vesa mounting pattern as below
